CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Patent Application No. PCT/CN 2011/074427, filed on May 20, 2011, which is hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates to the technical field of communications, and in particular, to an intelligent power distribution system and method.

BACKGROUND OF THE INVENTION

Along with the advent of the era of third-generation mobile communication technologies (3rd-generation; 3G for short), communication devices become more and more intelligent, which have higher requirements on conventional power distribution, and therefore, a brand new design idea of power distribution emerges, that is, intelligent power distribution implemented through electronic switch technologies, control technologies and monitoring technologies. A power distribution box for the intelligent power distribution is capable of providing excellent value-added services for clients, and output capacity of power distribution branches may be set and managed locally or remotely. In a system using a novel intelligent power distribution box, a power supply is distributed by the intelligent power distribution box and then supplies power for each electric device. A remote management platform performs management, such as monitoring power distribution situation and configuring circuit breaker capacity, on the intelligent power distribution box through a dedicated management network.

In the prior art, the configuration of the circuit breaker capacity of the intelligent power distribution box may be implemented locally or remotely. When the circuit breaker capacity is configured locally, a visual configuration tool (Commissioning Tools), such as a notebook computer or a palmtop (Personal Digital Assistant; PDA for short), may be used to manually configure the switch capacity of the intelligent power distribution box locally according to the actual load situation of the device. The specific configuration procedure includes: first, an engineer manually collects power requirements of electric devices before a system is powered on; configures the circuit breaker capacity of each power supply branch of the intelligent power distribution box by using a configuration tool through a local terminal or by configuring a dual in-line package switch manually; and then, starts the intelligent power distribution box to supply power for the electric devices. When the circuit breaker capacity is configured remotely, a remote management background may be used, so as to configure the switch capacity of the intelligent power distribution box at the remote background according to load situation of the device. The specific configuration procedure includes: first, an engineer manually collects power requirements of electric devices before a system is powered on; configures the circuit breaker capacity of each power supply branch of the intelligent power distribution box by using a configuration tool through the remote background; and then, starts the intelligent power distribution box to supply power for the electric devices.

In the prior art, before configuring the circuit breaker capacity of each branch of the intelligent power distribution box, it is required to collect information of the electric devices manually, and then configure each branch of the intelligent power distribution box separately. Ports of the intelligent power distribution box need to be correspondingly configured for the electric devices, so that the configuration procedure is complex. Errors easily occur in the remote configuration and cannot be found, resulting in that a circuit breaker of the intelligent power distribution box cannot function correspondingly. When load capacity changes, reconfiguration is needed, and automatic configuration according to actual capacity cannot be achieved.

SUMMARY OF THE INVENTION

In this case, the foregoing step 101 may specifically include:

-   -   if the first load identification unit receives, through the load         identification bus, the notification that the electric device is         powered on sent by the second load identification unit, sending         the notification that the electric device is powered on to the         management module through the monitoring management bus;     -   after the first load identification unit establishes a         connection with the second load identification unit through the         load identification bus, acquiring the information of the         electric device from the second load identification unit through         the load identification bus; and     -   sending, by the first load identification unit, the information         of the electric device to the management module through the         monitoring management bus.

Embodiment 4

FIG. 4A and FIG. 4B are a flow chart of an intelligent power distribution method provided in Embodiment 4 of the present invention. As shown in FIG. 4A and FIG. 4B, on the basis of Embodiment 3, the intelligent power distribution method may specifically include:

Step 201: A management module establishes a connection with a power distribution monitoring module of an intelligent power distribution box through a monitoring management bus, instructs the power distribution monitoring module to control a certain power distribution switch module of the intelligent power distribution box to be turned on, so as to supply power for a rear end connected to a port of the power distribution switch module; where a supply current may initially be the maximum current of the power distribution switch module.

Step 202: The management module establishes a connection with a first load identification unit through a monitoring management bus, notifies the first load identification unit that a power distribution switch module of the intelligent power distribution box is turned on.

Step 203: The first load identification unit determines whether the rear end of the turned-on power distribution switch module finds that the electric device is powered on. If the rear end of the power distribution switch module finds that the electric device is powered on, a second load identification unit on the electric device starts to work and notifies, through a load identification bus, the first load identification unit of finding that the electric device is powered on, and step 204 is executed; if the rear of the power distribution switch module does not find that the electric device is powered on, the first load identification unit is unable to receive and find information sent by the second load identification unit on the finding electric device, and after waiting for a period of time, the first load identification unit notifies, through the monitoring management bus, the management module that no electric device is found; and step 208 is executed.

Step 204: After the first load identification unit receives the notification of finding that the electric device is powered on, the first load identification unit establishes a connection with the second load identification unit on the electric device through the load identification bus, and acquires information of the electric device, such as a device type and a power demand level.

Step 205: The first load identification unit sends, to the management module through the monitoring management bus, a notification of finding that the electric device is powered on, so as to notify the management module that a port corresponding to the power distribution switch module has an electric device and the electric device has been powered on.

Step 206: After the management module receives the notification of finding that the electric device is powered on, the management module establishes a connection with the first load identification unit through the monitoring management bus, and acquires the information of the electric device collected by the first load identification unit.

Step 207: After the management module acquires the information of the electric device, the management module establishes a connection with the power distribution monitoring module of the intelligent power distribution box through the monitoring management bus; the management module controls the power distribution monitoring module to configure an over-current point of the power distribution switch module connected to the electric device, and the procedure ends.

Step 208: If the management module receives, from the first load identification unit, a notification that no electric device is found, the management module determines that no electric device is found at a port corresponding to the power distribution switch module of the intelligent power distribution box; the management module may establish a connection with the power distribution monitoring module of the intelligent power distribution box through the monitoring management bus, and control the intelligent power distribution box to turn off the power distribution switch module for which no electric device is found, and the procedure ends.

FIG. 5 is a schematic diagram of an application scenario of the intelligent power distribution method provided in Embodiment 4 of the present invention. As shown in FIG. 5, it is assumed that the power distribution switch module of the intelligent power distribution box is an electronic power distribution switch, for example: a port corresponding to an electronic power distribution switch_1 is connected to an electric device_1, and an operation flow of the electronic power distribution switch_1 of the intelligent power distribution box is described as follows:

The management module acquires, from a storage unit of the intelligent power distribution box, configuration information of the electronic power distribution switch_1, such as a device type and a power demand level (the intelligent power distribution box may be configured by default when being used for the first time), controls, through the power distribution monitoring module of the intelligent power distribution box, the electronic power distribution switch_1 of the intelligent power distribution box to be turned on; configures an initial over-current point; controls, through the power distribution monitoring module of the intelligent power distribution box, the electronic power distribution switch_1 of the intelligent power distribution box to be turned on, so as to supply power for the electric device_1 connected to the electronic power distribution switch_1; connects a −48 V power source to the electric device_1, so that a second load identification unit B of the electric device_1 starts to work and notifies a first load identification unit A in an intelligent power distribution system that the electric device_1 is powered on. At the same time, the management module notifies the first load identification unit A that the electronic power distribution switch_1 of the intelligent power distribution box is turned on. The first load identification unit A, after receiving information that the electric device_1 is powered on, may acquire, from the second load identification unit B of the electric device_1 through a load identification bus, information of the electric device_1, such as a device type and a power demand level. Thereafter, the first load identification unit A may notify the management module of the information of the electric device_1, and meanwhile, the management module may learn that a port corresponding to the electronic power distribution switch_1 of the intelligent power distribution box has an electric device_1, as well as the information of the electric device_1. Then, the management module compares collected actual configuration information of each power distribution switch module_1 with corresponding configuration information saved in the storage unit of the intelligent power distribution box, and when the actual configuration information is not consistent with the corresponding configuration information, updates the configuration information saved in the storage unit and, according to the information of the electric device_1, configures an over-current point of the electronic power distribution switch_1 by the power distribution monitoring module of the intelligent power distribution box; and if the actual configuration information is consistent with the corresponding configuration information, keeps the configuration information unchanged.

For another example, assume that a port corresponding to an electronic power distribution switch_2 of the intelligent power distribution box does not connect to an electric device, an operation flow of the electronic power distribution switch_2 of the intelligent power distribution box is described as follows:

The management module controls, through the power distribution monitoring module of the intelligent power distribution box, the electronic power distribution switch_2 of the intelligent power distribution box to be turned on, so as to supply power for the electric device_1 connected to the electronic power distribution switch_2, and connects a −48 V power source to a rear end. At the same time, the management module notifies the first load identification unit A that the electronic power distribution switch_2 of the intelligent power distribution box has been turned on. The first load identification unit A starts to wait for the second load identification unit B of the electric device reporting information of an electric device, and because no electric device is found, the first load identification unit A cannot receive information that an electric device is powered on during a period of time, so that the first load identification unit A may send, to the management module, a notification that no electric device is found. The management module, after receiving, from the first load identification unit A, the notification that no electric device is found, learns that no electric device is found at a port corresponding to the electronic power distribution switch_2 of the intelligent power distribution box. Then, the management module may establish a connection with the power distribution monitoring module of the intelligent power distribution box through the monitoring management bus, and control the electronic power distribution switch_2 of the intelligent power distribution box to be turned off, so as to stop supplying power for the rear end.

In this embodiment, the information of the electric device is acquired from the load identification module through the management module, so as to supply power for the electric device automatically, control an over-current point of the power distribution switch module automatically configured in the intelligent power distribution box, and control the circuit breaker capacity of the intelligent power distribution box; thereby reducing manual involvement during the power distribution, reducing a requirement on installation personnel of the intelligent power distribution box, and improving the installation efficiency and accuracy.
